Calcifert LS11
Calcifert LS11 both neutralises soil to maintain a balanced pH and contains 11% SO3 to help address the widespread sulphur deficiency on UK farmland. Calcifert LS11 is suitable for all cropping situations that have a requirement for both soil neutralisation and a Sulphur supply. The high percentage of Calcium Lime will optimise the soil pH, being pure high reactivity Calcium Carbonate, making more nutrients bio available. The Calcium Sulphate portion of the product will supply much needed plant available Calcium and Sulphur which are commonly undersupplied in crop nutrient management plan.
Recent data suggests that following a dramatic reduction in atmospheric deposits over the last 30 years, up to 85% of arable land and 88% of grassland, is deficient in sulphur, with some soils now at critically low levels. Sulphur is an essential nutrient required for the healthy development of all plants and vital to efficient nitrogen utilisation. Calcifert LS11’s sulphur content is coupled with high reactivity calcium carbonate – making it very effective at neutralising soil acidity and maintaining the right pH level to optimise fertiliser and nutrient efficiency leading to better quality and yield of crops.
Trials of Calcifert LS11 application have shown:
- Strengthening of the plant’s physical structure, helping to protect against disease and use sunlight and nutrients more efficiently
- Improvements to cereal yield where there was a sulphur deficiency
Calcifert LS11 is suitable for all crops and is best suited to spring application but is also suitable for autumn drilled oilseed rape and grass reseeds. As with all Calcifert products, it is supplied in 600kg bags and can be spread on farms using a conventional fertiliser spreader.
